While his boyhood club is now the richest on the planet, White is making his own way in business and believes City boss Mancini has done the right thing scrapping players like Mario Balotelli, 21.

For the 96 goal Maine Road hero - who scored a personal best of 18 for the club in the first season of the Premiership - was not a fan of Mario's antics at Eastlands and David said: ‘I would have to agree with scrapping Balotelli.

‘He was a problem character to deal with and it's the right decision that he is no longer at the club.'

Bookmaker William Hill official FA Cup betting partner took the famous trophy to White's salvage yard just a stone's throw from rugby league's new Salford Reds stadium to get his verdict on the televised clash being one of the few past players still around to have scored for both teams taking part.

At boyhood club City from 1985 to 1993 scoring 96 goals, White was exchanged to Leeds for £1.2 million rated David Rocastle in 1993 and scored 10 goals for the Elland Road outfit during his injury plagued two seasons with them before moving to Sheffield United in a £500,000 transfer in 1995 and finishing his professional career with them in 1997.

His England debut shirt from a 1992 away game against Spain, adorns his office wall, along with other memorabilia from his glittering career.

Looking around his office David said: ‘Moving forward on the rest of the season Mancini may have to make more changes, but when behind United in the Premier League not replacing Ballotelli was an odd decision.

‘On the wall behind you is a picture of the Manchester City legends, but the current team would all be on that now as they have won the Premier League.

‘We have great international players at the club, but you have to admire what has happened over the road at United as they have just kept on playing and you can never expect them to lie down and die.

‘City on the other hand has evolved over the past 10 years with different money coming in and the level of players coming in has stepped up.

‘But with players of that calibre come the problems as it's not always easy to mould them into a team.

‘Yaya Toure was magnificent last year, but it is not always possible to carry on that level of performance every season.

‘His game is so reliant on energy and fitness levels that he must rest at the end of this season.

‘The performance away at Southampton was the worse game City had played for a long, long time.

‘He could change 10 or 11 players in that team and Leeds will still be facing 11 opponents with points to prove to be in the team.

‘They will simply be too much for my other old club Leeds - I don't expect anything other than a City win and reckon it will be 3-0 or 3-1.

‘But Leeds will be tough and they will give them a game as Neil Warnock has got results wherever he has been.

‘He has a formula that works for him and it will be old fashioned, no nonsense football.

‘Sami Nasri and David Silva are great players, but it's difficult to fit them both into a team.

‘And James Milner is one player who would always be in my team and I am sure he will be back in this tie.

‘The manager can pick whatever team he wants and get a result - that is the quality in depth they have in the squad.

‘The truth is the Premier League has probably slipped away, so privately Mancini must think that the FA Cup is the biggest chance of silverware they have this season.

‘I can certainly see four or five changes and Leeds are just going to suffer as they are getting City on the back of a terrible result, so they have something to prove.

‘By the manager's reckoning only two players played well at Southampton, so he will have to drop a few.

‘They struggled in Europe and a lot of that was down to tinkering with the team. In the Champions League you need to know who your best 11 are and then you need to back them.

‘We didn't get through one game without changing the left back and you have to be stable in defence when you are playing against quality opposition.

‘It took Chelsea forever to win it and we did have a difficult draw.

‘We've got one young lad working here who had a £4 seven game accumulator with William Hill on matches last week and he won £8,500 and he reckons City will walk it this weekend.

‘I for one reckon he'll be right again and we're way off having to scrap the manager.'
